Structural studies of bis(μ2-acetophenoniminato)-bis(tricarbonyliron) by NMR and X-ray diffraction: deviations from symmetry in anti and syn isomers
Andrzej Zimniak , Janusz Zachara
AbstractTwo distinct structural isomers obtained in the reaction of 1,4-dimethyl-1,4-diphenyl-2,3-diazabuta-1,3-diene \(CH3)(Ph)CN\ 2 with triiron dodecacarbonyl were separated, characterized by NMR, and their molecular structures were determined by X-ray diffraction. Only idealized symmetry in both resolved anti and syn forms have been observed. Geometry analysis indicated in the syn form a substantial deviation from symmetry, especially in the peripheral region of the molecule. This deviation is preserved in solution, as demonstrated by 13C NMR.
